The input signals for ‘Auxiliary system ready’ are
given partly through the Remote Control system
based on the status for:
• gas supply system
• fuel oil system
• lube oil system
• cooling water systems
and partly from the ECS itself:
• turning gear d<strong>is</strong>engaged
• main starting valve ‘open’
• control air valve for sealing air ‘open’
• control air valve for air spring ‘open’
• auxiliary blowers running
• hydraulic power supply ready
Monitoring systems
In addition to the PMI off�line system required
for the installation of the ME engine, PMI on�line
and CoCoS�EDS can be used to improve the
monito�ring of the engine.
A description of the systems can be found in
Chapter 18 of the project guide and in our publications:
P.367: ‘PMI System Pressure Analyser’
and
P.413: ‘CoCoS, Computer Controlled
Surveillance’
The former <strong>is</strong> also <strong>available</strong> at the Internet address:
www.manbw.com under ‘Quicklinks’ →
‘Technical Papers’ in the ‘Libraries’ category from
where it can be downloaded.
Instrumentation
Chapter 18 in the Project Guide for the specific
engine type includes l<strong>is</strong>ts of instrumentation for:
• The -GI engine
• The CoCoS�EDS on�line system
• The class requirements and MAN B&W’s requirements
for alarms, slow down and shut
down for Unattended Machinery Spaces
Engine and Compressor Interface
Page 9 of 11
The needed gas compressor inlet engine varies
from 200 to 250 bar, depending on the engine
load.
Based on the speed / load setting signals coming
from the -GI, the compressor control will regulate
the gas pressure accordingly.
If the gas pressure inlet <strong>is</strong> not at the necessary
pressure level, the engine will change over to a
fuel oil operational mode.
ME Shut�down on Alarm System
In addition to the ME engine shutdown, the alarm
system gas limitations for high / low gas pressure
<strong>is</strong> incorporated in the engine control system as
alarm for gas leakage in the piping and exhaust
gas receiver and lack of pilot oil injection.
Compressor Control
The high gas compressor <strong>is</strong> provided with alarm
and shutdown in the internal control system.
All operating conditions are being monitored internally
in the compressor such as cooling water, gas
compressors, speed, etc.
